bar to work upward and unlock the knuckle. I overcome this. objectionable feature by providing a projection or shoulder 7 on the rear side of the lifter pin and an opposing shoulder 1 on the frame. \Vhen the pin is lowered, the T head will slide 'rearward in the slot and bring the shoulder 7 beneath the shoulder l and any upward movement of the locking bar will be stopped when these shoulders engage each other. When the lifter pin 7 is raised, however, its'lower T-shaped extremity, will rise in the diagonal- T-slot 4& carrying the shoulder 7 away from beneath the shoulder l and the lifter-pin may then be raised andwhen its T-head reaches the upper end ,of the diagonal T- slot, it, will carry the locking bar 5 upward with it.

In [the following explanation of the operationof this device, I will assume that two couplers are attached to cars in the usual way and holding the carstogether. -Inorder to utnlock these coupler-sand allow the cars to'separate, the three arm lever may be manually operated by means of its upper arm 8 or the pin lifted by theusual means (not shown). This will raise the lifter pin 7, i".s lower end rising in the diagonal slot et and lifting the looking bar 4, as heretofore explained, which will free the knuckle. 2, allowingit to swing outward and release the companion coupler. As the carsseparate, the releasing lever ll-on the opposite coupler will, by the action of the spring 13, swing outward into the now empty jaw and its rearwardly extending arm 12 will ralse'thelifter pin and locking bar by means of the three arm lever, thus automatically unlocking the knuckle on this coupler and allowing it to be swung open by a trigger l7 pivoted in the frame, engaging a notch 19 in the knuckle, and actuated by a spring 18.

it often happens that the engine will be pushing instead of pulling the train when the cars are to be uncoupled and the cars will not separate until the engine is stopped. it has been the custom for the brakeman to manually hold the coupler unlocked until the cars separate, and the knuckles open. In this device a shelf or ledge 20 is provided in the frame, and when the locking bar 4 is raised it is lifted at one side instead of directly in line with the center of gravity. The pin 7 will be caused to swing over and deposit the bar 4: uponthis shelf, thus unlocking the knuckle and allowing it to open when the cars separate. On the return of the knuckle tolocked position, the arm 3 will pass under the locking bar 4 and a'lug 1.") on the upper face oflll'e arm will engage a recess min the lower side of the locking bar, carrying it off the shelf 20 and allowing it to drop in'front of the arm 'to lock the knuckle;

' q hat l claim is:'-

- 1. A car coupler, comprising a frame hav- 'ing aws spaced apart, a knuckle pivoted in one aw. an arm on the knuckle swinging within the frame, a vertically and laterally movable locking bar-t0 engage and hold the arm. a fixed shelf-1n the frame-at one side of the bar, a nnfnually operated lever connected tothe bar to lift the same and deposit it on the shelf, a spring-actuated lever to engage and move the manually operated lever andto/hold the same in inoperative position, said spring-actuated lever being engaged and moved out of engagement with sald-manually operated lever by the knuckle of another coupler.

A car coupler, comprising a frame having'jaws'spaced apart, a knuckle pivotedin one of the jaws, an arm on the knuckle swingingrivithin the frame, a locking bar pivoted in the "frame at one end and vertically movable at. the other end, a lifting pin-attached to the bar by a T-head engaging an upwardly and forwardly inclined T-slot in the bar, and opposing shoulders on the frame and pin, engaged when the T-head is in the lower end of the slot and disen-- gaged'by forward movement of the head-in the slot when the pin is lifted.

3. A car coupler, comprising a frame having jaws spaced apart, a knuckle pivoted in one jaw, an arm on the knuckle swinging within the frame,,a vertically and laterally n-iovable locking bar to engage and hold the arm, a lifting pin-connected to the bar at the lower end and adapted to swing laterally, means for lifting and laterally moving the pin applied to the same at one side of its center of ravity, and a shelf at the same side of the ar on which the bar is deposited by the pin.

4. A car coupler, comprising a frame having jaws spaced apart, knuckle pivoted in one jaw and having an arm swinging in the frame, means for locking the arm, a vertically movable pin to lift the locking means and release the arm, a releasing lever piv oted in the other jaw, a spring to open the knuckle, a spring to operate the releasing lever, an arm on said releasing lever, and a lever pivoted in the frame having one arm engaging the pin to lift the same and having another arm engaged by the arm on the releasing lever.

A car coupler, comprising a frame having jaws spaced apart, a knuckle pivoted in one jaw, locking means for the tail of the knuckle, a releasing lever pivoted in the other jaw, springs to swing the knuckle and lever.outward, an arm on the releasing lever,

a 'vert-iea'll movable pm to raise the locking means an release the knuckle and a three arm lever pivoted in the frame and having onthe releasing le one arm engaging the pin to vertically move the same, a second arm enfiaged by the arm ver to o d the pin and position and a third locking means in raised arm to manually operate the three arm lever.

6. A car coupler, comprising a frame having jaws spaced apart and provided with a shelf and a web, a knuckle pivoted in one jaw, a releasing lever pivoted in the other jaw, an arm on the knuckle and an arm on the lever, a locking bar pivoted to the Web at one end and vertically movable at the other end and also having an inclined T-slot, a lifting pin having a T-head engaging and traversing the T-slot, shoulmrrs on the pin and frame adapted to engage when the T- head is in the lower end of the slot, a lever pivoted in the frame engaging the pin at one side of its center of gravity to lift the pin end swing the same laterally to deposit the bar on the shelf, said lever the arm on the releasing lever, and a projection on the top of the arm on the knuckle to engage the bottom of the bar to move the latter oil from the shel' In testimony whereof I alfix my signature in presence of two Witnesses.
